Something a little different for me. 61 images focus stacked, only minor cropping.

Very nice! 61 images!! I don't know anything about stacking, but would it look that much different if you used something like only 15 or 20?

I think it would actually, at this distance the DOF is extremely narrow. Having said that, I don't know that it NEEDED 61 images either. This is the first one I've ever attempted so to an extent I was just playing around with it to see what the result would be. I haven't done the calculations to know exactly how much stepping was needed. I may do it again lol. This is a new area for me.

I always get confused: Does "70% crop" mean 70 percent of the area is left, or 70% is thrown away?

And then there is option #3 which I use; Disregarding any really deep technical stuff:
My monitor is 1920x1080. I view my shots in a window not full screen. That window shows the full frame as being at 22% zoom level which I equate to percentage of actual size. I assume that if I zoom in to 50% then the portion of the shot I see is 50% actual size. So I say I cropped at 50%. This completely ignores how much I threw away or kept. I am assuming a one to one correspondence for picture pixels mapped to screen pixels when viewed at 100% which may not be a reality. Works for me anyway.

This is not what is was asking about, and your option #3 will not help me. When I see a shot posted here, the poster says it is cropped 70 percent, I want to know how big the remaining image occupied on the uncropped image. Wiki, as somebody wrote here, says one thing. Some people here use the opposite meaning. I guess I will have to ask this question every time I see a posting and want to know what the original looked like.

I know. I think to get exactly what you want people would have to list post crop/pre-resize dimensions with picture when posted to the forum. I always resize to 1280xwhatever prior to posting and let the site software do any adjustments. Haven't looked at exif of posted pictures to see what is retained.

Just Lr and Ps. Lr to edit tones, sharpening, etc and Ps for the stacking.

I'm with you.....you can't base percentages on your own monitor: especially these days with monitor resolutions and print dimensions being so varied. As someone who's profession is graphics and web development, for a statement of "my image is cropped 70 percent": I take that to mean 30% of the image is remaining. If the statement was "I cropped in to 70%", then I'd take that to mean 30% of the image was discarded. My basis is always 100% of source resolution: makes more sense since I then know what to work with for intended output size (and how much scaling/ppi/dpi there is).

If I mention a crop, I usually say something like "this is 25% of the original image." I think that's pretty clear. But then there's the infamous "100% crop." I do use that to indicate that the image I've shared is a 1:1 pixel relationship with the original image; i.e. cropping to 1200x800 and exporting the image at that size.
